MetLife has an established and robust whistleblowing process, where employees can anonymously report concerns as to any breach of our Code of Conduct, which would include any breach of modern slavery law

Correction: Towards the end of the document, the statement says, "MetLife has an established and robust whistleblowing process, where employees can anonymously report concerns as to any breach of our Code of Conduct, which would include any breach of modern slavery law." This shows that MetLife does allow whistleblowing but the document does not go into detail about any grievance mechanisms.
